"HUMAN! COME FAST! THERE IS A GUY IN MY HOME CLAMING TO BE ME!!!" Papyrus' voice rang thru the phone almost destroying my ear drum.

"Calm down, It's called a mirror..." I said sleepishly and let out a small gigle.

"IT'S NOT FUNNY! AND WHAT'S THE MATTER?! YOUR VOICE SOUNDS TERRIBLE!" He exclamed.

"Oh, you know, just woke up" I yawned.

"HUMAN ITS TWELVE A CLOCK- ANYWAYS COME HERE FAST!" He continued.

"Paps, your over reacting" I sat up in my bed.

"NO I PROMISE! LOOK" the phone went quiet for a while.

...

A "Sup?" Was herd from papyrus side of the phone sounding an awfull lot like Sans but it had Papyrus voice.

"OMFG!!! STAY RIGHT THERE!" I ordered papyrus thru the phone.

The covers flew up in the air when I rushed out of bed, I trew on a hoodie over my sleeping clothes and hurried out the door.

~|Time skipp brought to you by: reader-chan yawning while reading the word yawn|~

I knoked nervusly on the door.

"OH, YOU'RE FINALLY HERE! HES BEEN SUFFECATING ME WITH BAD PUNNS SINCE THE MINUTE HE ARIVED!!!" He complaned while opening the door.

As soon as I took a step inside I felt something different.

"Paps, where's Sans?" I asked.

"I DON'T KNOW, I CAN'T SEEM TO FIND HIM!" He answered.

"Wha-" i started but was interupted when a tall figure coming down the stairs.

I loked closer at him, furrowing my eyebrows I relized his clothes also reminded me of a sertand skeleton. A orange hoodie, long brown shorts and old trainers. As I glanced back at his face I relized that he was inspekting aswell, it was only then I really came found of that I was wearing my short sleeping shorts, whitch to say atleast were...short. The realization tinted my cheaks slightly red.

Papyrus, the hoodie wearing one,  met my eyes and tilted his head.

"(Y/n)?" He asked comfused.

"Ehhh, yeah?" I said uncoftrably 'how did he know my name!?'

"Are you allways waring those clothes in this universe?" His eyes looked to be looking spesificly at my shorts only deepening the red shade on my face.

"Ehhhhhhh, what?" 'Did he say universe? Who the hell is this guy?'

"Are you still dating my brother?" Now every inch of my face was red out of enbarrasment as I relized that he was talking about Sans.

"Eeehhhhhhhhhhhhhhh" 'What the ffffff am I supose to answer!?'

A loud buzzing sound came from my phone.

Saved by the bell.

"(Y/n) are you there!?" Alfys voise rang thru the room.

"Wait a sec" I looked at the two Papyruses.

"What do you mean? What happened?" I asked a little worried since it weren't her usual stuttering voice.

"I-I may have acsidently opened a portal into another u-universe..." Her voice was normal again but it didn'take me any less worried.

"What do you mean another universe?!" I exclamed, the hoodie wearing papyrus came running up to me and the phone at the mention of "another universe".

"Let me hea-" he started but I put a finger over his mouth hushing him angryly. (Im a boss ass bitch!)

"Wait Alf, I'll put you up on speaker" I pushed down the button so that all three of us could hear.

"So, explain" I talked down to the phone.

"I-I was working on a experement but some how I opened a portal" She said unsurely.

"S-so keep your eyes open if somthing unusual happens" she requested making a sight eskape my mouth.

"And what would that be?" I asked as I looked at the hoodie papyrus.

"O-oh w-whell, dubbelgangers to the normal monsters could have been sucked in by the portal into our universe" she explained, i nodded.

"And what would they be like?" I asked furter.

"O-oh they would look just like any monster from this universe"

I nodded looking at the papuruses who starired into the phone.

"A-and enen tho they look alike, they act completly different"

I nodded yet again and got eye contact with the hoodie wearing one.

"B-but thats only in the worst c-case-"

"Alf I think we may have a problem..." I interupted her as I took a hold of Papyrus hoodie and starded moving towards the door.

"Come on, were going to Alf" I looked at the tall skelletons.

"Yeah, you better Ketchup other me" the hoodie wairing one said to his dublicate clearly making him angry while I tryed to hold in a higgle as we continues towards Alphys lab.
